Editor's Notes
- [This is meant as the agenda slide for my section – the “tell them what you’ll tell them” slide]IT Must respond by building a platform for delivering an enterprise class of services – “enterprise class is built into the platform” enabling developers to be compliant with corporate policies, while meeting their own individual business needs.
- Migrate a Mainframe App to a PC. Done. Right? Nope.Before PC’s took off, no one really knew if they were a “business tool” or something else. At first, this was ok, people would use PC apps for personal productivity, but “real work” was done on the mainframe.This sounds like today’s attitudes.
- I think this is a good time to mention why there is a lot of friction right now. It’s not just the increased demand, or the transparency. It’s the fact that a touch/speak model of computing is much more intimate. And, when apps don’t align with that intimacy, it’s a more jarring experience than in the past (when an app was just hard to use).
- The interaction model – it’s not about menus and drilling in deeper and deeper to get more information. It’s about stream-of-consciousness “in the moment” activity. So, capturing a meeting. Entering data at point of occurrence. Time/Location driven event response. Etc. Take for example a customer who believes that smart mobile notifications can get customers to pay their tax bills earlier. Mobile behavior is different.
- Each of these points – delivering many, quickly, easily change, many models is a multiplier – each turns 1 project into many deliverables/apps.
- This is in many ways “culturally driven” as much as “technology driven”.Of course the App Store follows the long tail model pioneered by Amazon Books – it’s the same thing, but for software. The difference is, we also use software within the enterprise, and the App Store is setting people’s expectations on availability, awareness, ratings, etc.
- This enterprise stuff has become uncool to speak about – governance, compliance, risk management, resiliency, privacy… but it’s critical. For the obvious reasons, but also because they make sure to protect the enterprise and enable better business.
- This is the summary slide, setting up the questions slides that sets up Manmohan
- These metrics to optimize to are critical, but not at the expense of the user experience.These get delivered in the platform.On point #5, use as example: How do you understand root-cause “integration” errors, rather than chase 100’s of app errors?
- We heard why enterprise mobile For next few minutes - how
- Propose a framework with 3 phasesStrategy is overarching…In the first phase –Focus on Target audienceand value Business case and business modelsIn the second the focus is on –Actually designing and implementing the APIIn the third phase, the focus is on –Operating your API platform, tracking key KPIs and making it easy for app developers to adopt your API
- Decide who are your target app developersCould be internal, external or partnersDetermine the access policies and terms of serviceRate limits, breadth of access, business modelShould provide valuable function or data or service to the target audienceExpose a business capability as an API – valuable data or valuable functionExamples:The Intuit Partner Platform (IPP) enables developers to integrate with rich financial and transactional data through REST-based APIs and offers unparalleled reach through Apps.com.2 API’s one to integrate QUickBooks, second to access to financial and transactional Data From 19,000 Financial Institutions
- An API not backed by great service is a kind of like lipstick on a pig – i.e. it’s still a pig

- As David said its not about the medium, but about the experience. API are crucial to delivering that experience.APIs are a lot like building a UI since it targets the developersMock up -> Try it out with and try it out with sample data And with feedback refine it further until the goals are metAnd that’s when you move on to implement the APIAdded benefit of test and doc is now in sync with implement
- Your product (your API) needs to be credible, relevant, and differentiated. You essentially create a façade – a holistic view of what the API should be from the perspective of the app developer and end user of the apps they create. Power the API with data stubs and iterate till you are satisfied with the API. Then use mediation to integrate the API façade with the systems of record.“Design Patterns – Elements of Reusable Object-Oriented Software (Erich Gamma, Richard Helm, Ralph Johnson, John Vlissides)
- GIVE CHOICESData formatsXML, JSONProtocolsREST, SOAPSecurity/authentication optionsOAuth2, OpenID connect, HTTP basic authAdvanced optionsStreaming for low latency accessResponse CachingBatch API vs. Real-timeSupport partial response by adding optional fields in a comma delimited list. Use limit and offset to make it easy for developers to paginate objects. APPLY OCCAM’s RAZOR PRICINCIPLEIf two API’s are equivalent, simpler one is preferred – discard anything more complex
- Why REST has been preferred?-> rise in use of rest->75% of all public API’s use REST (programmable web)Since REST takes advantage of the same Internet mechanisms that are used to view regular web pages resulting in faster implementations and easier for developers to understand. REST/JSON vs. XML60% of all new API’s support JSON.30% of all new API’s support only JSON.BUT a good API understands its audience-> your audience may prefer SOAP-> good examples of this are: a) exchanging documents with strategic partners b) Financial data: Strikeiron is only SOAP and Xignite in financial services (has a choice of SOAP and REST API’s)c) Salesforce provides both SOAP and REST API
- Limited bandwidth, processing powerIntermittent connectivityUse JSON to allow apps to specify size of data Use GZIP to compress responsesOAuth2 to avoid password sharingCache your responses if appropriateCaching means lighter load on your data centerOr use CDN’s for faster response timesChatty APIs and how to deal with it : Netflix example-> design a REST API-> provide shortcuts for returning composite response-> consider providing an SDKTesting by simulate latency. Slow down your backend service and verify UX
